To all "whom it'mayconcem:

Be it known that I, ORVIN'H. CHANDLER, a citiz'enof the-United States,residing at Clinton, in the county of Laurens and State of SouthCarolina, have invented new and useful improvements in 'iooth-Brushes,of

whiledt is being used.

Vihth'these and other ends in v ew which will readily appear as thenature of theinvention ishetter'understood, the same consistsmthemprovedconstruction and novel arrangement and combination of parts which willbe hereinafter fully described and par ticularly pointed outin theclaims.

In the accompanying drawing has been illustrated a simpleand preferred:form of the invention; it' being, however, understood thatno limitationis necessarily made to the precise structural details therein exhibited,

, but that changes, alterations and. modifica tions within the scope ofthe invention may be resorted to when desired. p H

In the drawing, Figure 1 1s a side view, partly in section.) of a toothbrushembodymg the invention. Fig. 2 IS aside vlewshowing the brush.member detached, partly in section; "Figt3 is a perspectivevlewgillustrating slightly modified form of a shield member. :Fig. 4; isaside view illustrating a modified formof the brush member. Fig. 5 is atransverse sectional-view taken on the plane indicated by. the line 55in Fig. 1.

Corresponding arts in the several figures are denoted by liejch-aracters of reference, The improved brush includes a handle andoperating member'A, a shield member 13 and a brush member C which areadapted tobe associated together for operation in such a manner thatthey-maybe readily separated for-cleaning or other purposes. I

. The handle member surrounds a stem or .s'haftl having a wormor-spiral2 formed vided'at one end with 4 the lugs thereonin anysuitable manner, and, proa sleeve-or. collar 3. The handle proper 4 ismounted forlongitudinally 'slidable movement up'on the worm shaft, 1which it engages in any suitable -manner to impart rotary or oscillatorymover-- ment thereto.

' The shield member B includes a cup shapedshield 5 having alongitudinal recess 6 and preferably provided with laterallyextendingside flanges7 said shield is also provided with a longitudinallyextending tubular shank or socketfiwhich may be circumferentiallymilled, as shown at 9 or otherwise fitted to form a convenient grasp forthe fingers of the person using the brush the shield may alsobe providedwith an outwardly ex-. tending lug 10 adapted to be grasped. between theteeth of the person using the brush for the purpose of steadyin'g themovement of the latter.

The brush member 0 includes a stem or shank 11' having a cylindricalbrush 12 which may be ofany desired size and shape andwhich may bemanufactured in any sum able and- .convenient manner. The shank 11 isprovided at its inner end which is the end oppositeto that carrying thebrush with a eylindrical'portion 16 adapted for insertion into thetubular sleeve or collar 3 carried by the shaft 1, and having a notch 17adapted to be engaged-by I 18 suitabl "connected with the sleeve 3;;forexample, means of the screw 19Wl]i(ih serves to secure the sleeve 3 uponthe worm carrying shaft -1.

The shield member and thebrush member 'may be readily assembledby'inserting the shank 11' ofthe brush member -.endwise through thetubular shank8 of the shield member; .when thus assembled, thecylindrical brush will be partly accommodated in the recess 5 of theshield, While the notched end of the shank 11 will extend a sufiicientdistance beyond the tubular shank to enable it to beareadily introducedinto the sleeve 3 where itiis engaged and held by'the catch 18. Thelatter thus serves to lock the parts together in operative relationwhen, after placmg the desired tooth wash or detergent material upon thebrush within the'shield, the device is applied to the teeth where it maybe held and grasped securely] by inserting 10 betweenthe teeth.The-shield may a o be graspedby'the tubular shank 8 a catch orfastjening member by the fingers of-one hand of the operator who, withthe other hand reci rocates the handle member 4 longitudinal y, thusimignated 20, is made relatively short androunded, and unprovided withthe lug 10 to be enga ed by the teeth; this form of shield will beoundpreferable for operating upon the back teeth and upon the backs of thefront teeth. This form of shield involves the 'use of a modified form ofbrush which will be seen at --21 in Fig. 4 of the drawin s. In practice,it will be referred to put up tIie improved tooth brus es in setsincluding several shield members and brush members of different sizesand shapes'in connection i with a single operating handle with whichthey may be used interchangeably.

It will be readily understood that no limitation is made to the preciseforms of shields and brush members herein shown, as the same may bevaried indefinitely for particular uses. These and other structuraldetails are capable of being widely modified within the scope of theinvention.

Havin thus fully described the invention, what I c aim as new is 1 1. Ina device of the class described, a cupshaped shield havin a tubularshank, a

' brush disposed in sai shield, a stem integral at one end with thebrush and fitted for rotation in the tubular shank, said stem being ofgreater length than the shank with its opposite end projecting beyondthe rear end of.

said shank and formed to provide a locking portion of the brush stemWhic member, a worm shaft having atits forward I end a sleeve receivingsaid locking member and provided with a coacting locking mem-- her, anda worm-engaging reciprocating handle.

2. In a device of the class described, 'a-

Worm shaft having a terminal sleeve, a catch operating through thesleeve, a fastening member securing the catchupon the sleeveand thelatter upon the worm shaft, a cupshaped shield having a tubular shank, abrush disposed in said shield, a stemintegral at one end with the brushcore and extending through and beyond the shank, the opposite projectingend of said stem fitting in said sleeve and being provided with a keepermember enga ed by said catch, and a handle member slida bly engaging theworm shaft to im art oscillatory movement to the latter.

3. n a device of the classdescribed, a

shield member having a tubular shank,lat

erally extending flanges, and an outward extending tooth engaging ludisposed inter mediate the flanges, in. com ination with a cylindricalbrush mounted in the shield and having a stem fitted for rotation in thetubular shank, a worm shaft having a terminal sleeve equipped with acatch en aging the extends through the tubular sleeve, thus assemblingthe shield member, the brush member and the worm shaft; and a handleslidably engaging the worm shaft to impart oscillatory motion thereto.

- In testim'ony whereof, I affix my signatur in presence of twowitnesses.
